Types of dental implant

Dental implants are classified as endo-and juxta-osseous bone. It is true that for reasons of terminology are new names for the classification of dental implants: bifid, needles, thin ridges, multidimensional ... however, they all obey the same laws.

Implants that do not penetrate the bone, but that line the surface are called in France, subperiosteal, and have been given the most accurate name juxta-bone. Anglo-Saxon countries are calling this implant surface subperiostal. Juxta-osseous implants or subperiostiales, were introduced in 1940. Metallic elements are introduced under the mucosa and contacting the jaws resting or jaw. Are made in the laboratory of prosthesis, using models of the jaw, mostly performed with chromium-cobalt-molybdenum, and are sometimes coated with carbon or ceramic.

The morphology may differ in some points, but all implants that are beginning to penetrate the thickness of the bone are provided, and simply endo-osseous implants, which are necessary for the use of the scalpel and the stripping of the mucosa; These implants can be metallic, glassy carbon, ceramic, semi-organic material or biological. Although there are many classifications of endo-osseous implants, states generally that dental implants are divided into cylindrical, threaded, a thin blade and crest.
